1930. Serial This application is a division of my application forLetters Patent filed September 19, 1929, Serial No. 393,640.

The main object of this invention is to provide in a spring structure animproved brace whlch 18 effective in supporting or ment of my inventionis illustrated in the accompanying drawings in which:

Fig. 1 is a fragmentary plan view of a spring cushion structureembodying the features of my invention.

Fig. 2 is a fragmentary section on line 2-2 of Fig. 1.

In the embodiment of my invention illustrated the body springs l are ofthe hourglass type, the outer springs being secured to the top borderframe 2 by means of clips 3 and 4, the clips 4c being elongated toengage a pair of adjacent springs and also serve to connect the braceelements as will be hereafter described.

The bottom rim 5 illustrated is of the S type, the inner channel beingclamped upon the bottom coils of the outer spring while the outerchannel is adapted to receive the upholstery.

Certain of the springs are connected by tie or cross members 6 ofchannel cross section, these members being secured to the springs byclamping upon the intermediate coils thereof.

Opposite sides of the top border frame are tied together and braced by across brace consisting of brace members 7 which are connected toopposite sides of the border frame by means of clips 8, these membershaving laterally turned ends 9 engaged by the clips.

The members 7 have coupling engaging arms 10 at their inner endsdisposed laterally and projecting in opposite directions, these armsbeing engaged in the coils of the coiled spring coupling member 11. Theend coils of this couplin member are engagcd with the top coils ofadjacent springs.

The members of the top frame are thus braced against lateral movement,at the same time its vertical movement or the vertical movement of thesprings is not materially restricted by the brace.

I also employ in this structure jointed braces connected by couplingmembers 12 and 13, the coupling member 12 being secured to the member 6while the coupling member 13 is secured to the clip l. This brace is thesubject matter of claims in the original application.

I have illustrated and described my improvements in an embodiment whichhas been found to be very practical. I have not shown variousembodiments and adaptations of which it is capable as it is believedthat this disclosure will enable those skilled in the art to embody oradapt my improvements may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. The combination in a spring structure of a plurality of coiled bodysprings, a border frame, a cross brace therefor comprising a pair ofmembers connected to opposite sides of the border frame, and a coiledspring coupling member for said brace members, said brace members havinglaterally disposed coupling engaging members engaged within the coils ofsaid coupling member, the coils of the ends of said coupling memberbeing engaged with coils of adjacent body springs.

A spring structure comprising an as sembled set of body springs and aframe element, a brace connected to said frame element and disposedbetween adjacent body springs, and a coiled spring coupling memberconnected at its ends to a pair of the body springs, said brace having alaterally disposed portion engaged within the coils of the couplingmember.

In witness whereof I have hereunto set my hand.

FALCONER OBRIEN.
